FEEDING APPARATUS FOR PUNCHING-NIACHINES.

SPECIFICATION forming part of Letters Patent No. 759,308, dated May 10,1904.

Application filed September 16, 1903. Serial No. 173,415. (No model.)

To all zoll/07u it may concern:

Be it known that I, JAMES A. REEVES, a resident of Alliance, in thecounty of Stark and State of Ohio, have invented certain new and usefulImprovements in Feeding Apparatus for Punching-Machines; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to an improved feeding apparatus forpunching-machines, the object of the invention being to provide improvedmechanism of this character which will permit both sides or edges of aplate to he punched at one time parallel to each other in either astraight or curved line and to provide imlgiroved mounting` for thefeeding-table which will permit of the adjustment of the track to anydesired curvature to feed plates curved in any are of a circle.

With this object in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts, aswill be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view illustrating myimprovements. Eig. 2 is a side view partially in section, and Fig. 3 isa view in section on the line a.' a' of Fig. 2. Eig. f1 is a plan viewwith the truck removed, and Eig. 5 is a view in cross-section of thesame.

1 1 represent the rails of a track on which the wheels 2 of a movabletable or platform 3 are mounted to run.

rlhe rails 1 1 are secured to plates L1, and the latter have curvedslots 5 at both ends to receive upright pins 6, integral with or fixedto blocks 7, suitable cotter-pins 8 being passed through pins 6 aboveplates 4L to prevent accidental displacement of the latter.

Midway between the blocks 7 are blocks 9, having lugs 10, between whicha ratchet-bar 11 is secured by bolts 12, and through threaded openingsin the alined blocks 7 and 9 screwrods 13 are passed and are mounted inframes 14, secured upon timbers 15 or other support to hold the frames,and the latter prevent longitudinal movement of the screw-rods,compelling longitudinal movement of blocks 7 and 9 when the rods areturned to give to the rails 1 and ratchet-bar any desired curvature, butmaintain them always in parallelism. Suitable hand-wheels 16 are securedon the outer ends of rods 13 to facilitate their being turned and theconsequent adjustment of the track. It will thus be seen that thecurvature of the track can be made in exact accordance with thecurvature of the plate to be punched, and hence the feed of the tablewill exactly compensate for the curvature of the plate.

On the forward truck-axle of the table or platform 3 arms 17 are pivotedand carry a the plate will be simultaneously punched whether the platebe straight or curved, the track being' adjusted to the proper curvatureto compensate for the curvature of the plate and insure its proper feedto the punches.

The table or platform 3 is preferably fed by means of a pinion 20,driven by any desired source of power and engaging a rackbar 21, carriedby the table.

A great many slight changes might be made in the general form andarrangement of the parts described without departing from my invention,and hence I would have it understood that I do not restrict myself tothe precise details set forth, but consider myself at liberty to makesuch slight changes and alterations as fairly fall within the spirit andscope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. In a feeding apparatus, the combination with a feeding table orplatform, of rails, wheels supporting said table or platform and mountedon the rails, and means for bending said rails to any desired curvature.

2. In a feeding apparatus, the combination IOO with a wheeled table orplatform, of rails on which the wheels of the table are mounted to run,and screw-rods Connected with said rails and adapted to bend them to anycurvature.

3. In a feeding' apparatus, the combination with a movable table orplatform, and wheels supporting the same, of rails on which the wheelsare mounted, a ratchet-bar between said rails, ratchet mechanism carriedby the table or platform to engage said ratchet-bar, and means forcurving said ratchet-bar and rails in parallelism.

4. In a feeding apparatus, the combination with a movable table orplatform and wheelsv supporting the same, of rails, a ratchet-barbetween them, blocks supporting said rails and ratchet-bar, screw-rodspassed through said blocks and adapted to adjust the rails andratchet-bar to any curvature, and ratchet mechanism on the table orplatform to engage the ratchet-bar.

5. In a feeding apparatus, the combination with a movable table orplatform and wheels supporting the same, of rails, a ratchet-bar betweenthem, blocks supporting said rails and ratchet-bar, screw-rods passedthrough said blocks and adapted to adjust the rails and ratchetbar toany curvature, ratchet mechanism on the table or platform to engage theratchet-bar, a rack on said table or platform, and a driving-pinionengaging said rack to feed the table on the rails.

6. In a feeding apparatus, the combin ation with a movable table orplatform and wheels supporting the same, of rails, a ratchet-bar betweenthem, blocks supporting said rails and ratchet-bar, screw-rods passedthrough said blocks and adapted to adj ust the rails and blocks to anycurvature, ratchet mechanism on the table or platform to engage theratchetbar, a rack on said table or platform, a driving-pinion engagingsaid rack to feed the table forward, and a punch on each side of saidtrack.

In testimonjT whereof I have signed this specification in the presenceof two subscribing witnesses.

JAMES A. REEVES.
